You are correct, the current version of the web application does not support the changing of the base symbol on military layers. This function will be interduce in one of the future versions of the web application.
In the meantime contact us directly using
m...@gs-soft.com and we will provide you with a solution to edit base symbols on existing military layers in the MilX Format.
Please do not hesitate to contact us should you have further questions on
